INTRODUCTION <br />:::fi.;iw':(1JF3';::::.u:Yn::2:.'::::::::~::SKVS:C'].::'s:18~Y'„RPii.'zA'o.L:3:21:•:B:Y::$'S:'ii.`ii."w:::At21a:a:8:LN."^:::T.d::1:RSY.QiZ)iS ~m~.~y.."Ot~.'K4' °Y <br />In October 1980, Chimney Rock Coal (now Kaiser Ventures, Inc.) began a hydrologic sampling <br />program. The program involves sampling the various chemical and physical constituents at <br />numerous surface and groundwater stations. The mine site is located approximately 20 miles <br />southwest of Pagosa Springs, Colorado on Highway 151. The mine facilities are situated adjacent <br />to Stollsteimer Creek which is a perennial stream draining the area. Stollsteimer Creek flows to <br />the southwest into-the Piedra River which is a tributary of the San Juan and Colorado Rivers, <br />respectively. <br />The objectives of this program are designed to gather information on both surface and <br />groundwater regimes and to assess the potential impacts of mining and reclamation activities on <br />the existing hydrologic balance. To this end, samplings have been conducted to assess surface <br />water flow and groundwater movement. Water chemistry has also been analyzed at both surface <br />and groundwater stations. <br />Mining activities were suspended at the site during 1985 and the mine was in temporary cessation <br />between 1985 to 1990. In 1990, Kaiser began final reclamation of the surface facilities area and <br />Revision 1 pit area. This activity was completed during 1991, at which time all facilities <br />associated with mining (except sediment control structures) were removed and all disturbed lands <br />were reclaimed. <br />Sampling locations which have been utilized during the program are described below: <br />S-1 Surface water station located on Stollsteimer Creek 1/4 mile above the mine <br />facilities. The station was selected to assess baseline conditions of stream quality <br />and flow above mining facilities. <br />S-2 Surface water station located on Stollsteimer Creek below the surface facilities and <br />mining activities conducted on the Barren Ridge Area and above the inlet of the <br />sedimentation ponds which control site runoff from the Revision Area No.l. The <br />station was selected to assess effects of surface operations on stream quality and <br />flow. <br />S-3 Surface water station located on Stollsteimer Creek one mile below all mining <br />activities. The station was selected to assess the overall effects of mining on <br />stream quality and flow. <br />1 <br />DC-1 Deep Creek surface water station located on Deep Creek at Highway 151. The <br />station was selected to assess overall effects of mining in Revision Area No. 2 <br />located in the Deep Creek drainage. <br />1991.053/3/01-30-96(9:59am) 1 •, <br /> <br />
